Be' itknown that I, WALTER W. LAND; sleuren, u citinen of the United Staten, residing nf: Norwoofl7 Hamilton County, and

Stute '0i Ohio,'hare invented n new and useful Addinff und Culculatin r Machine, of which the following is :1 specification.

This invention relates to adding'nnd calcnlgltin machines.

Anfo'jectof the invention is to provide nov'e'l and elicient equipment' for use in an nfdlingund cnlculotinf machine to facilitotetlio operation of tlie n'izihino in multipliction'-rorl': where u, constant multi- .p'lcund'isi employed' indifferent exam iles.` In ti'e spl'cificnform shown in the rawingsitfe invention is embodied-inn machine c. of'thejDnlton type., 'although' the invention is notiestricted tense in n machine o f that srecilfic construction. It is nppiirent that tie invention muy. be used in` other machilies in whichv'thfe diierentiol mechanism is cooperatively related Vwith a' 'cnrria'ge under contijol of nl imerul keysend in which tl'ie'ldiferentinl stopsl are. set. by. the coopernition of the carriage'andtheJrcya J1'0tlier 0bje;c;t of 1the iniention 'is to provid novel melons 'whereby the pins in the trolilnjersely moruhle cnrriufre may be reso turmfl 'to' their nor'mal'fo'r idle osit-ions,

as'nn incident. to the'movenient o 'the carringe4v to ite home or starting. position, or lwtgnsdesired.

Another 'object of theinvention is toppo- 36 vide, a novel und' simple means` for controlling and postioningthe differential mechanism to' facilitate multiplication where constant multiplicanfl. is c rnplc'iyed.A Although the number of 'digits o'r figures in 40 differentmultplignds vary, the utility of the invention is not diminished, for in such enses cipher ping: muy he in the'higher nu'meijicnl orders in the differential' mechnnisin leaving the :ic-live figmrs ofthe multiplicand in the lower numerical orders'in the differential mechanism where the multipli'cond includes lees than the whole number 'of digits or'figuree rerluired to .place one such iligitor figure-in 'en nun'iericiil order.

The sereni 30 snp orts n bell 375'0 'eratively su' ported' behind the" plate 25., en the'lii Z24 is p 21', lthe arm 36 of the be ing theflink 137. 'A 'platev 38 is connected 'with ttl'ielovver'end-of the'flink 37 by a screw Atl9'iin'd is guided in its vertical movement y ascrew 40, passin Vthrough a slot 41 in saidiplatc andsecure to astationary art of the machine. When the link 37 is rmsed., it lifts the plate 38 from the position shown infig. 4 to the position shown in Fig. 5. When the plate 3S is raised a shoulder 42 thereon en aves a latch member 43 and is yieldingly elli in connection with the latch 4member by a spring 44. The slot 41 is wide enongf'hjbo permitthe necessary oscillation ofthe plate-38 for-movement into and out of engagement with the latch member 43. The carriage 2 su portsva projection 45 which passes over t e upper end of the plate 3S when said'plate ism its lower position; that tsrwlien the resent invention is out of use.

But when tie multiplying key-21 is depressed and, as n consequence, the plate 38 is latehed with the latch member 43, the upper end'o said plate'38 is in position tobeengaged by the projection 45 on the carriage 2 so'ae to stop the carriage in its tabulated 'movement. The momentum of the carrie e ln its tabulatedmovement `will unlatch t e shoulder 42, permitting vthe plate 38 to drop -to ifa'c'nitgina position when the multiplying Vthe exampl 26 will pass over the' 'v' arm-33 ie'lbellfcriiiilrr lever32- extends rear-I wa'rdl'yfinto 'a slot" inthenpperl 'end of a link moved reerwardly extends under the latch :mn 16 (Fig. ll.'

key 21 is released, leaving the cnn-inge under control of the numeral ke mechanism. The screw 39 exten-ds throng n slot 46 in the supporting plate und is connected with an arm 47 pivoted on n support 48. The arm 47 has an extension 49 underthc universal escapement bar l14, so thatwhen the multiplying key 21 is depressed, the'pawls 50 pfthe 'esapement mechanism are rendared llgectiveand the carriage is permitted to lmore by one movement. until stopped g contect of the projection 45 with the a utment plate 38. Then the nmltiplyingr key 2,1V4 is released, and thc link 42 drops to its initial position, the eecnoement pan'ls 50 reeengage with the controlled part of the escapement mechanisme The carriage is 'thereby retained in one position for ns many successive operations of the adding und recording mechanisms as maybe needed in e fbeing worked. 'lllhonsteppinp` `movements -of the carriage toward Vhi her orders under control ofthe zero key otgthe Amachine is needed, such'stepping movement be obtained by operation ofthe zero key -in the usnal way. After. the desired number ofo'perations have been'performed, the can lriaoe is lreturned to its overthrow position in t Ae usnalway, in'whioh position the car riage will be retained by engagement of the arm 16 yviththe shouldered part 17, ready for another operation nndel' 'control of the multiplying mechanism.

A pin51 on the arm 33 of the lever 32 As a consequence of the rearward movement of the lover arm 33, imparted thereto by the shoulder 35 on thelink 24, the nrm 16 will be raised out of latching engagement with the shouldered part 17 whenever `the multi plying key 2l is depressed. This release o1 the arm 16 from engagement with the shouldered part 17 is timed so thnt the stop plate. 38 becomes latched with the part 43, and so that the escnpement pawls 50 are disconnected from the controlled part of the escapement, before the arm 16 is disengaeed from the shouldered part 1'?.

'To prevent rebound of the cnrriage to wards its home position, when the morement of the carriage is stopped by the stop plate 38, an abutment under control of thl1 multiplying mechanism is --provicled A3 shown a latch 52 is irotnllyisupported by :i stationaryr part of t ie machine and is inox'- able to and from position to engage behind the :plo'ection 45 on the carriage?, (Figs. 3, 4 an 5). A spring 53 connected with the latch plate 52 actuates the latch )lute to position behind the projection 45. llhen the multiplying mechanism is not in use the latch plate 52 does not operate. A link 54 operating in a guide 55, has its u per end pivotedto a Ylatchrplntc 52 and its lon'cr end provided with a projection 56, extending llO under un arm of the plete 38. Thus, when the plate 38 is in its lower position (Figs. :md 4), the link 54 is held down and the latch plate 52 is held up revcnting said latch plate from engaging hehind the projection 45. So when the machine is used for ord:- nary adding and listing purposes, and when the multiplying mechanism 1s not in use, the latch plate 52 is not operated; but as un incident to the depression of the niultiplyinfr key 21,1md when the latch plate 38 is raiser the spring 53 depresses one end of the latch plate 52 to the position shown in Fig. 5. The projection on the carriage 2 passes beyond o. shouldered part of the latch plate 52 so that rebound of the carriage toward its home position is revented. It is desirable to ilock the numeral ke mechanism against operation when the mu tiplying mechanism is placed in use. As shown (Fig. 6 n locking bar 57 extending transversely o the levers of the key mechanism 3 is pivotelly mounted on'supports 58 in connection with a fixed part 59...'Ihe levers of the key mechanism Shave shoulders 60. A spring 61 in connection ,with the lock bnr 57 normally holds the lockbcr -close- A.against the plate 59 behind and vout o ffthe` wayiof theA shoulders .60, leaving the; key

62 nj'connection with the lock-bereextende Lthroughv a-slotin the 'plate 59 irl-position to be engaged by a 'cani 63 supported by the carriage 2z when the cerriagefis in itsA overthrow position. The cam 63 does not engage the projection 62 at any time when the carriage is out of its overthrow poslton. Thus', 1when-the multiplying mechanism is 4not in use, the carriage is not retained in its overthrow position, and the cam 63 does notfretain-engegement with the projection 62, s e consequence of which theflock bnr 57 does not interfere with the operation of the keymechanism 3. .But so long as the. carriage is inits overthrow position, the, cam 63 by en agement with the rojection 62, holds the ock bar 57 forever y in opposition to the'spring 61., holding the lock bnr V57 immediately above in the .path of movement of the shoulders 60, thus prevent-l ing `.operation of the numeral key mecha.- nism sc'long as the carriage remains in its overthrow position. g

The device by which the pins in the can ringe 2 are depressed, ns an incident to the movement of the carriage to its home or starting position when the multiplying mechanism is not in use and whichis disubled so that it will not depress the pins in the carriage when the multiplying mechn- .msmis placed in use,'1s en ,important fenture off. the 4present invention. A plate 64 is supported for' vertical movement and ad justment above thehome or starting position of the carriage 2. Said plate has projections 65 on its rear end operating in slots 66 n stationm plate7 and has similar projections 67 on its forward und operatingt m slots 68 in the plate 59. Springs 69 tend Lo misc the plate 6-1 high enough to permit the carriage 2 .to pass under the plate without depressing the ins 1 in the carriage. lf the late 64 be hdld in its lower position (Eig. the raised pins in the carriage will contact with the upturned edge 70 on the plate 64 as the carriage moves toward its home or starting position, and the raised pins will be depressed thereby. When the machine is used for ordinary work of addition or calculation, the plete 64 is held in its depressed or lower position; so that thc pins 1ere pressed down in the carriage every time the carriage returns to its homc or starting position. But when the multiplying mechcnlsm is placed in use, the plaie 6i is raised so that the set up pins in the carriage 2 will not engage the plate 64 as the carriage moves thereunder.

The cem device for pressing the plate 6s .down in opposition to the power, of the,

L59. .Cems72 on.the rear .ends of the members 71 and similar cams 73.011 theforward endsot said members are arranged to. o er- .ate' against the uper wells ofthe slots wit in seid members when `they are moved rem-- wardly. The cern members 71 rest upon the plete 64, so, that, rearward -movement .lof .said cem members will push. the plete-64 downwardly. to. .position .to be' engaged by the pins 1 when thecarriage2 moves to its home or stsrtingposition. .A link 74 has its rear end pivoted to the cem members 71 and itsV foi-werd,y end operating within e gplde 75 and provided with a key 76. A s oulder 77 on lthejlink 74 is arranged tobe Vengaged with the guide75lwhen the link 74 isl pushed rearwardly, in order to hold the pin restoring pletev 64 in its lower position when 1t.1s esired to restore the pins 1 to unset positions at each operation of the machine.

One of the projections 67; of the pin restoring plate 64. is above a projection 78 (Figs. 6, 7, and 8) on a. lever 79. The inner end .ofthe lever 79 is pvoted at 80 and the outer `end of ysaid lever extends. over the forward end of the arm 16 in iront of the pivot .1.8 of said arm (Fig. l). As a. consequence of this arrangement, depression of the pin restoring plate .6s b operation of the 4key device 'T4-76 not on pushes down the pins 1 finthe carriage 2 ut also raises the arm 16 out of engagement with the shouldered part17. his permits the carriage the members 71 move,.so ns todepressto move over from its overthrow osition to its normal or home osition. e inachine'is thus normalize read for use in ordinary work of addition or ca culation, so that the ins 1 will be depressed at each return of t e carriage 2 to its home or startin position.

rom the fore oing it is clear that my in ventioii greatly acihtates the worlr of mul tiplication in any machine in which a constant multiplicandmay be set up and used successively in different examples. The invention requires com uratively few addtional parts in the mac ine and requires only slight modification of themachine in whic the invention is embodied. I contem late varying the form and arrangement o the parts and the relative positions thereof to any extent desirable to accommodate the invention to the mechanismsin any machine in which it is to be used.4 I do not restrict myself .to unessential features either in the construction, arrangement or mode of operation, but make claim to the invention com mensurate with the scope of the novelty and utility thereof.
